DAS Active 21” Subwoofer - EVENT-121A

The DAS EVENT-121A is a professional-grade 21 inch active subwoofer designed to deliver deep, high-output bass with precision and power. Ideal for concert sound, live venues, nightclub, DJ, and touring applications, this powered subwoofer features a direct-radiating, rear-loaded design that enhances low-frequency clarity and impact.

Designed for live sound reinforcement, concert touring, large mobile DJ setups, club installs, festival stages, and fixed installations in theatres, arenas, churches and houses of worship, the EVENT-121A offers flexible deployment options. Whether you're ground-stacking under flown arrays, building directional cardioid sub arrays, or integrating into portable PA systems, this subwoofer delivers consistent performance across diverse venues.

A built-in Class D amplifier (3200W peak / 1600W continuous) and advanced DSP processing ensure tight, distortion-free sub-bass, even in high-SPL environments.
